更换 Qt 后 nomacs 打不开问题

• 新建脚本，替换环境变量

  vim /home/KangHua/tool/nomacs-wrapper.sh
  

#!/bin/bash

# 1. 设置环境变量
export PATH="/opt/Qt5.15.2/bin:$PATH"
export QTDIR=/opt/Qt5.15.2
export LD_LIBRARY_PATH="/opt/Qt5.15.2/lib:/usr/lib/aarch64-linux-gnu:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/opt/Qt5.15.2/lib/pkgconfig:$PKG_CONFIG_PATH"

# 2. 启动程序并传递所有参数
# "$@" 会原封不动地把所有传入脚本的参数（即 %F 代表的文件路径）传给 nomacs
# 使用 exec 可以让 nomacs 进程替换当前的 shell 进程，更省资源
exec /usr/bin/nomacs "$@"

chmod +x /home/KangHua/tool/nomacs-wrapper.sh

• 替换启动方式为脚本启动

  vim /usr/share/applications/nomacs.desktop
